Hyphae, loaded with CTC under pH 6. 8 condition and then grown in pH 8. 0 medium for a little while to destroy the apical acidification, could gave very diffuse fluorescence images of CTC membrame bound Ca〓 and vermiform fluorescence spots due to mitochondrias under pH 6. 8 no longer were clearly distinquished, which implied that besides mitochondrias, other cellular organelles with Ca〓 also were stained with CTC. Thus mitochondrias are not the only one intracellular Ca〓 storage, endoplasmic reticulums and Golgi bodies in the same zone may be also the Ca〓 storages. But the extreme apical zone under 2μm of the growing hyphal tip was still almost devoid of stain under pH 8. 0.The CTC fluorescence was concentrated in the subapic zone beyond about 2μm from the tip and then gradually became lower behind about 40μm from the tip. These results did not support the hypothesis which suggested that the cell wall vesicles in the extreme apical zone were intracellular Ca〓 storages.

将菌丝在pH6.8条件下负载CTC,再置于pH8.0培养介质中短暂生长一会儿以消散菌丝顶端的酸化区域,则CTC膜结合Ca〓呈现弥散的荧光影像,在pH 6.8培养条件下显示的蠕虫状的线粒体荧光斑点不再能够清晰辨认,说明除了线粒体之外,还有其它含Ca〓细胞器,也被CTC染色,线粒体并不是细胞内唯一Ca〓库,还可能包括内质网、高尔基体等细胞器,但菌丝最顶端2μm以前的细胞壁泡囊区域不能被染色,最大荧光强度仍位于菌丝顶端2μm以后区域,约45μm以后荧光变弱,实验结果不支持细胞壁泡囊为菌丝胞内Ca〓库的假设。
